While loops [ID:802] (7/7)

in series: Python Beginners - Loops and Iteration

(Showmedo is undergoing major changes. To report any problems viewing the videos please email us and include browser and OS specifics. Cheers - Kyran.)

The 'while' loop is different to the 'for' loop. Rather than iterating over a sequnce of items, instead we repeatedly run a block of code under the control of a logical test. The 'while' look can be controlled using the 'break', 'continue' and 'else' statements just like the 'for' loop.

Here we use a simple example of the 'while' loop to build a list of user-input (obtained using 'raw_input').

Well done once again.


Lesson was precise and clear.


Ian - enjoying the series immensely thus far. I am learning python because of automated testing initiative at my work place. Up to recently, most tests were manual, so my java, C++ skills slid to nil. So this is a great refresher course on OO, and I'm finding that I like python better than the aforementioned languages I learned previously. Thanks a lot! Keep up the good work!

Thank you. This was useful, although going into this exercise I had assumed that

a, b = b, a+b

was the same thing as

a = b

b = a+b

after some experimentation, trying to recreate the Fib. sequence program, I figured out that a,b = b, a+b doesn't change the values of the variables until after both statements are executed.


Great series covering the power of loops. I will be using for and while loops heavily to make automated Network Weekly operation scripts.

Thanks Ian keep up the great work,

-Mark


great! thank you


Hello Ian,

Great video. Very well explained. understood everything. I implemented and ran your code. I think that this code will help me with my upcoming assignment. Could you maybe explain to me this part of the 4.6 Fibonacci:

print b,

a, b = b, a+b

Thanx


I realized that even though there is very little code and everything can be read clearly, you have used different character sizes in the different videos. I always appreciate big characters as they are more readable. Excellent videos!


Very clear and straightforward.

Thanks!

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Ian
